Derby shoppers using local branches of Sainsbury's supermarkets are being warned about the recall of several products because they are a potential health risk.

According to the Food Standards Agency, Sainsbury's is recalling a number of their products because Listeria monocytogenes were found in some of them.

This is a bacterium which can cause serious health problems. An agency spokesman said: "Symptoms caused by this organism can be similar to flu and include high temperature, muscle ache or pain, chills, feeling or being sick and diarrhoea.

"However, in rare cases, the infection can be more severe, causing serious complications, such as meningitis.

"Some people are more vulnerable to Listeria infections, including those over 65 years of age, pregnant women and their unborn babies, babiels less than one month old and people with weakened immune systems."

Sainsbury's is involved in the product recalls.

He added: "If you have bought any of the above products do not eat it. Instead, return it to the store from where it was bought for a full refund.

"Sainsbury's is recalling the products and point-of-sale notices will be displayed in all retail stores that are selling these products. These notices explain to customers why the products are being recalled and tell them what to do if they have bought the product. No other Sainsbury's products are known to be affected."
